- LCC -BEAM-RCLLWEICHT LIFTER. 3

To all whom it may concern. r

. Be it known that I, OTHO OSULLIVAN, a citizen of the United States,residing at Stonington, in the county of'New London and State ofConnecticut, have invented a new and useful Loom-Beam-Roll-vVeightLifter, of which the following is a specifi cation By way of explanationit may be stated that in looms which handle broad silk-or othermaterial, the warp upon the beam roll isheld back to the proper tensionby means of a weight 'or a plurality of weights-sue pended from. aflexible element, the upper end-of'the' flexible element being securedto the loom stand and one or more turns of the flexible element beingpassed around-the beam roll. The weight thus imposed upon the'bea'm rollto tension the samevaries from twenty-five to one hundred pounds, andthis weight. must frequently be lifted by the weaver in'crder to releasethe tension on the beam roll. The weight and the flexible ele-' mentwhereby the same is suspended are in operators cannot manipulate them,or if the weightsare made in sections,a considerable amount of time isconsumed in removing theweights piece by piece.

The present invention aims to providea' simple structure whereby theweaver, by the movement of a foot and without so ling the hands, maymanipulate a tensioningfweight in a loom of the ClELSS'ClQSCFIbQd x Theinventlon'alms, further, to improve generally and to enhance the utilityof, de'-* vices of that type to which the present invention appertains.

With the above and other objects in viewwhich will appear as thedescription proceeds, the invention resides in the combinationandarrangement-of parts and in the Fur-y.

details of construction hereinafter described and claimed, it beingunderstood that changes in the precise embodiment of the inventionherein disclosed can be made within the scope of 'what is claimedwithout der' parting from the spirit ofthe invention.

In the drawings :Figure lshows the invention inside elevation, locatedadjacent the tensioning weight, the lifting head being depressed; "Fig.2 is a side elevation of the structure, the lifting head being shownelevated, in solid line; Fig. 8 is a cross sectionon the line 33 ofFig.2; Fig. 41s a perspective of the lifting head; Fig. 5-is' anelevation of the lifting liead,'fparts being broken away and sectioned;Fig. 6' is a perspective detail showing a-portion of the structureuponwhich thelatch is mounted.

In the accompanying drawings there is shown a' support 1 receiving'forrotation the trunnion 2 of a beam roll 3 about which is wound a flexibleelement t carrying at its lowerend a head 5"provided'with an eye '6adapted to engage a hook 7 equipped at its lower end with a stop 8, thestop 8 upholding a plurality of slotted weights 9. Lo-

cated below the stop 8 is a lifting device] which will, now bedescribed.

The lifting device comprises a supporting structurejincludi'ng a base 10notched at its ends as shown at 11 to receive screws ll'or the likewhereby the base may be secured to the floor. 10 is a trough'whichpreferably is V-shaped in cross section, the trough 12 beingprovidedupon its edges Withdugs 14. Pro

j'ectingfrom one lug 14' as'shown in Fig. 3 is an ear 15 and projectingfrom the trough 12 adjacent the longitudinal center thereofis an ear 16The trough 12 is provided along its'longitudinal'center with an opening17 Projecting rearwardlyfrom the trough '12 opposite to arms 18. H

The invention further includes a trough shaped'cap l9 which'cooperateswith the the opening; 1'7 are spaced trough 12' tofform a guide. The cap19' preferably isV Shaped'incrOSS section so that the cap and the'troughdefine a rec tangular socket as clearly shown in Fig. 3.

Formed integrally with the base shown in Fig. 3, is a lug 32. 3O 7 Thecap 19 is provided with lugs 20 cooperating with the lugs 14 and throughthe lugs 20 and 14 are passed securing elements 21 which may be screws.The cap 19 is shorter than the trough 12 so that an opening 22 exists atthe bottom of the" socket formed by the members 19 and 12. The trough 12and the cap 19 cooperate to form a tubular guide in which the liftinghead,

standard 24 there is a longitudinal slot 26,

the standard 24, at one side, and below the base of the slot 26 beingcut away as indicated at 27. Above the cut away portion 27, and at theupper end of the slot 26, the standard-24 is rounded as shown at 31'.

A, pivot element 28 passes through the ears 18 and constitutes a fulcrumfor alever 29, one end of which lies in the slot 26. Projectinglaterally from the lever 29, as

A pivot element 34 is mounted in the ears 15 and 16 and servesto supporta latch 33 provided at its lower end with a-finger adapted to engage thebase 10., At its upper end, the latch 33 terminates in a head V isplaced on the lever 29, the end 30 of the lever being elevated, the sameengaging the standard 24 at the upper end of the slot 26.

" In' this manner, the lifting head 23 is elevated, and the weights 9are raised. When the lever 29 moves downwardly, the lug 32 thereon willtraverse therounded or beveled edge 37 of the head 36 on the latch 33,the

510 latch swinging toward the body portion of the structure andultimately hooking over the lug 32. Inthis manner, the weights 9 will beheld elevated. In order to permit the weights to'move downwardly, thefoot of'the weaver is placed against the upper end of the latch 33, andthe same is swung to disengage thehead 36 from the lug .32.

Owing to the fact that the standard 24 is cut away as indicated at 27,the extent of h-possible upward movement of the standard is increased,the cut away portion indicated at 27 serving toreceive the lower edge ofthe end 30 of the lever 29 when the lifting head 23 is elevated. Whenthe lifting head is-depressed, the roundedportion 31 of the standardpermits a maximum downward movement of the lifting head. The opening 22serves to prevent an accumulation of foreign matter in the socket 1219,and therefore, the downward movement of the lifting head is not impeded.The finger 35 of the latch 33 engages the base 10 and holds the latch 33in an inclined position with respect to the vertical, so that the lug 32on the lever 29 will engage with the curved or beveled edge 37 of thehead 36 when the free outer end of the lever 29 is swung downwardly.Owing to the fact that the latch 33 through the medium of the finger 35is maintained in theinclined'position shown in Fig. 2, the'head 36 willhook over the lug 32 on the lever 29 by gravity, the use of springsbeing unnecessary. Downward movement of the free outer end of the leverbeyond a predetermined point is prevented by the end 30 of the leverstriking the trough 12 at the upper end of the opening 17.

From the foregoing it will be seen that I have presented in an extremelysimple and compact form, a means whereby the tensioning weights of a100m may be lifted and lowered readily, it being unnecessary to handlethe weight when it is desired to relieve the tension.

Having thus described the invention, what is claimed is '1. In a deviceof the class described, a base; a trough upstanding from the base andhaving a laterally projecting lug, there being an ear extended from thelug to the base and forming a reinforcement for the lug, the troughhaving an ear disposed approximately parallel to the firstspecified ear;a pivot element mounted in the ears;

a cap coiiperating with the trough to form a guide and having a lug; asecuring element uniting the lugs and alined with the lug carried ear; alifting head mounted to slide in the guide; a lever fulcrumed on thetrough and co'clperating with the head; and a lever-engaging latchmounted to swing on the pivot element.

2."In a device of the class described. a supporting structure includinga tubular guide having a longitudinal opening; a lifting head slidablein the guide; a lever entering the guide and having an opening, theinner end of the lever entering the opening and cooperating'with thehead, the inner end of the leverbeing adapted to rest against the guideat the lower end of the opening therein, to limit the downward movementof'the head and the upward swinging movement of the outer end of thelever;'and a pivot element permanently uniting the intermediate portionof the lever with the guide thus to hold the inner end of the lever atall times within the opening in the lifting head thereby to, prevent aremoval of the as my own, I have hereto affixed my signalifting headfrom the guide and to prevent ture in the presence of twowitnesses.
